What was the name of the 1876 Philadelphia event held for America's 100th anniversary?

The Centennial Exposition was the 1876 Philadelphia event held to mark America's 100th anniversary. Its formal title was the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine.

Held in Fairmount Park from May 10 to November 10, 1876, it was the first official world's fair in the United States. Nearly 10 million visitors attended, and 37 countries participated. The exposition displayed industrial machinery, manufactured goods, agricultural products, and new technologies.

The event is connected to the Declaration of Independence because Philadelphia hosted both the 1776 adoption and the centennial commemoration. Products associated with the exposition included Alexander Graham Bell's telephone, the Sholes and Glidden typewriter, Heinz ketchup, and Hires root beer. The later 1976 bicentennial and 2026 America250 continue the sequence of major national anniversaries.
